  Log Message:
  -----------
  [llvm][CodeGen] Fix the issue caused by live interval checking in window scheduler (#123184)

At some corner cases, the cloned MI still retains an old slot index,
which leads to the compiler crashing. This patch update the slot index
map before delete the recycled MI.
